본 발명은 철도차량대차 특히, 작동중에 일반적으로 직각 형태로 장치되는 대차부품에 대한 지지장치에 관한 것이다. 본 발명의 철도차량대차는 측방향으로 확장하고 종방향으로 일정 간격을 갖고 배열되는 한쌍의 휠세트(wheelset)를 통상적으로 포함하는데, 각 세트는 단부에서 휠 및 베어링장치를 고정하는 차축을 포함한다.The present invention relates to a railway vehicle bogie, in particular a support device for bogie components, which are generally arranged in a right angle during operation. The railway vehicle bogie of the present invention typically includes a pair of wheelsets that extend laterally and are arranged at regular intervals in the longitudinal direction, each set comprising an axle for securing the wheels and bearing devices at the ends. .

휠세트는 차측에 고정되는 베어링아답터에 의해서 차축에 지지되는 사이드프레임에 의해서 접속된다. 상기 프레임 및 휠세트는, 각단부의 인접부가 측방향으로 일정간격을 갖고 배열된 상기 프레임에 의해서 탄성적으로 지지되는 볼스터를 경유하여, 통상적인 방법으로 철도차량차체의 하부에 장치된다. 이러한 일반형태의 대차를 통상적으로 4륜대차(four wheel truck)라고 한다.The wheel set is connected by a side frame supported on the axle by a bearing adapter fixed to the vehicle side. The frame and the wheelset are mounted to the lower part of the railway vehicle body in a conventional manner via a bolster which is elastically supported by the frame arranged adjacently at regular intervals in the lateral direction. This general type of truck is commonly referred to as a four wheel truck.

철도차량이 철로를 따라 정상작동되는 중에, 상기 대차에 헌팅(hunting) 및 요우잉(yawing)현상이 발생된다. 상기 요우잉 및 헌팅현상을 취소로 하기 위하여, 탄성중합체 장치가 휠세트와 사이드프레임사이에 삽입되어 헌팅 및 요우잉 현상을 억제하므로서 휠세트 및 사이드프레임을 통상적인 직선철로를 따라 운행되는 경우 서로에 대해 일반적으로 직각관계를 유지하는 반면에 곡선철로를 따라 운행되는 경우 소정의 제한상태회전이 가능하게 된다. 상기 탄성중합체장치는 한쌍의 금속판사이에 접착 및 삽입된 탄성 중합체패트(elastomeric pad)를 통상적으로 포함한다.While the railway vehicle is operating normally along the railway, hunting and yawing phenomena occur in the trolley. In order to cancel the yawing and hunting phenomenon, an elastomeric device is inserted between the wheel set and the side frame to suppress the hunting and yawing phenomenon, so that when the wheel set and the side frame are driven along a conventional straight rail, While generally maintaining a right angle relationship with respect to the curved rails when traveling along a curved railroad can be limited rotation. The elastomeric device typically includes an elastomeric pad bonded and inserted between a pair of metal plates.

본 발명과 관련된 장치류가 미국 특허번호 제3,638,582호, 제3,381,629호, 제4,416,203호, 제4,363,278호 및 제3,699,897호에 밝혀져 있다.Apparatuses related to the present invention are disclosed in US Pat. Nos. 3,638,582, 3,381,629, 4,416,203, 4,363,278 and 3,699,897.

공지장치류의 각각은 철도차량에 대하여 일반응용이 부적절하다고 알려져 왔는데, 근본적인 이유는 탄성중합체패드가 소정의 기능을 수행하지 못하기 때문이다.Each of the known devices has been known to be inadequate for a one-railer for railway vehicles, since the elastomeric pad does not perform a predetermined function.

본 발명은 이러한 문제점을 해결하기 위하여 제안된 것이다. 이러한 문제점을 해결하기 위해서는 확고한 결합(non-sperating)관계가, 탄성중합체장치의 금속판과 베어링아답터와 사이드프레임의 접촉표면에서 확립되어야만 한다.The present invention has been proposed to solve this problem. In order to solve this problem, a firm non-sperating relationship must be established at the contact surface of the metal plate, bearing adapter and side frame of the elastomeric device.

만약 이러한 확고한 결합이 확립되지 않는 경우는 어떤 크기의 전단변위(shear displacement)하에서 탄성중합체장치와 대차부재의 접촉면의 분리가 발생되어 탄성중합체패드의 소정의 기능이 근본적으로 약화된다.If this firm coupling is not established, separation of the contact surface between the elastomeric device and the bogie member occurs under shear displacement of a certain size, which essentially weakens the predetermined function of the elastomeric pad.

휠세트와 사이드프레임의 상대회전을 억제하는 평면에 있어서 탄성중합체패드의 효과적인 강성이 감소되어 과잉헌팅현상이 발생된다. 또한, 접촉표면의 분리는 기차운행중 탄성중합체패드와 그것의 측 및 종방향접촉 표면에 피이닝효과(peening effect)를 초래하여 그것의 탄성특성을 상실시키므로 파괴되어 탄성중합체 장치의 적절한 작동수명을 감소시킨다.In the plane that suppresses the relative rotation of the wheelset and the sideframe, the effective stiffness of the elastomeric pad is reduced, resulting in excessive hunting. In addition, the separation of the contact surface leads to a peening effect on the elastomeric pad and its side and longitudinal contact surfaces during train operation, resulting in a loss of its elastic properties, thus destroying the proper operating life of the elastomeric device. Let's do it.

따라서, 본 발명은 기차운행중 접촉표면사이의 어떤한 분리도 발생되지 않은 확고한 결합을 제공함으로써 상기 문제점을 해결하고자 한 것이다.Accordingly, the present invention seeks to solve the above problem by providing a firm coupling in which no separation between contact surfaces occurs during train operation.

상기목적을 달성하기 위하여 사이드프레임 및 베어링아답터의 평접촉표면과 평접촉표면을 갖는 탄성중합체장치의 금속판이 제공된다. 탄성중합체장치는 사이드프레임의 받침대 정부내에 설치된 보어(bore)에 수용되는 외부돌출보스(boss)를 갖는 하나의 접촉 표면을 포함한다.In order to achieve the above object, a metal plate of an elastomeric device having a flat contact surface and a flat contact surface of a side frame and a bearing adapter is provided. The elastomeric device includes one contact surface having an external boss that is received in a bore installed in the pedestal part of the sideframe.

보스는, 보스를 수용하는 개구위에서 받침대정부(pedestal roof)에 고정되는 와셔에 견고하게 시이트(seat)되는 헤드(head)를 포함하는, 볼트와 나사조립되는 내부나선부를 포함한다. 나선 볼트가 보스의 내부나선보어에 견고하게 고정되어 탄성장치의 접촉표면이 받침대정부의 평접촉표면과 확고한 면-면결합상태를 유지한다.The boss includes an internal helix that is screwed with a bolt, including a head rigidly seated in a washer secured to a pedestal roof over an opening that receives the boss. The spiral bolts are firmly fixed to the internal spiral bores of the boss so that the contact surface of the resilient device is in a firm face-to-face engagement with the flat contact surface of the pedestal.

또한, 탄성장치의 반대쪽은 하부돌출나선스터드를 포함하는데, 나선스터드는 베어링아답터내에 형성된 내부나선개구에 나사고정된다.The opposite side of the elastic device also includes a bottom protruding spiral stud, which is screwed into an internal spiral opening formed in the bearing adapter.

스터드 및 볼트는 각각 동일한 방향의 나선을 포함하여 결합부의 해체를 방지한다. 탄성장치가 양쪽에서 나사고정되므로, 사이드프레임 및 베어링아답터에 대한 장치의 접촉표면이 분리현상에 반하여 유지되므로 표면사이의 어떠한 미끄럼도 발생되지 않는다.The studs and the bolts each contain spirals in the same direction to prevent disassembly of the coupling. Since the elastic device is screwed on both sides, no sliding between the surfaces occurs because the contact surface of the device to the sideframe and bearing adapter is held against separation.

이하 도면을 통해 본 발명을 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

본 발명의 장치를 포함하는 철도차량대차(10)이 제1도에 도시되어 있다. 단지 한쪽측부만 도시되어있는 대차(10)은 세로방향으로 일정간격을 갖는 휠세트(14)에 고정되는 한쌍의 사이드프레임(12)를 통상적으로 포함한다.A railway vehicle bogie 10 comprising the apparatus of the invention is shown in FIG. The trolley 10, shown only on one side, typically includes a pair of sideframes 12 fixed to the wheelsets 14 at regular intervals in the longitudinal direction.

휠세트(14)는 각각 외부단부에서 휠(18)및 로울러베어링(26)을 고정하는 차축(16)을 포함하고, 사이드프레임(12)는 내부에서 볼스터(24)가 스프링(22)에 의해서 탄성적으로 지지되는 볼스터 개구(20)을 포함한다. 볼스터(24)는 중앙판(도시되어 있지않음)에 의해서 철도차량차체(도시되어 있지않음)의 하부에 적절하게 결합된다.The wheel set 14 includes an axle 16 for fixing the wheel 18 and the roller bearing 26 at the outer end, respectively, and the side frame 12 has an internal bolster 24 by means of a spring 22. An elastically supported bolster opening 20. The bolster 24 is suitably coupled to the lower portion of the railroad car body (not shown) by a midplane (not shown).

제3도에 나타난 바와 같이, 차축(16)에 고정되는 베어링(26)은 사이드프레임(12)의 받침대정부(30)으로부터 하방으로 돌출한 받침턱(28-28)사이에 위치된다.As shown in FIG. 3, the bearings 26 fixed to the axle 16 are located between the supporting jaws 28-28 protruding downward from the pedestal part 30 of the side frame 12.

베어링아답터(32)는 베어링(26)에 고정되고 베어링(26)을 에워싸고 있다.The bearing adapter 32 is fixed to the bearing 26 and surrounds the bearing 26.

본 발명장치에 합치되는 탄성 또는 탄성중합체장치(34)가 받침대 정부(30)과 베어링아답터(32) 사이에 위치하여 대차운행중 휠세트(14)와 사이드프레임(12)가 면 또는 직각관계로부터 벗어나는 회전을 제한하도록 보조함으로써 대차의 과잉헌팅현상이 근본적으로 감소된다.An elastic or elastomeric device 34 conforming to the device of the present invention is positioned between the pedestal part 30 and the bearing adapter 32 such that the wheel set 14 and the side frame 12 are out of plane or at right angles during the carriage. By assisting to limit the rotation, excessive hunting of the bogie is fundamentally reduced.

또한, 탄성중합체장치(34)는 대차가 철도의 곡선부에서 운행될 경우 휠세트(14)와 사이드프레임(12)의 소정의 상대제한회전을 허용한다. 제4도 및 제5도에 도시된 바와 같이, 탄성중합체 장치(34)는 상부원형(금속) 판(38)과 하부원형(금속)판(40)의 맞서는 표면사이에 삽입되는 원형탄성 또는 탄성중합체패드(36)을 포함한다.In addition, the elastomeric device 34 permits a predetermined relative limit rotation of the wheel set 14 and the side frame 12 when the bogie runs on the curved portion of the railway. As shown in FIGS. 4 and 5, the elastomeric device 34 is a circular elastic or elastic material inserted between the opposing surfaces of the upper circular (metal) plate 38 and the lower circular (metal) plate 40. A polymer pad 36.

원할경우, 패드(36)은 아교 또는 다른 방법에 의하여 금속판(38)및 (40)에 부착될 수 있다. 또한, 패드(36)은 천연고무로 형성되어 반대힘이 적용되는 경우에 맞서는 면사이에서 전단으로 저항력을 제공하는 것이 바람직하다.If desired, pads 36 may be attached to metal plates 38 and 40 by glue or other methods. In addition, the pad 36 is preferably formed of natural rubber to provide resistance in shear between the faces facing the opposite force is applied.

상부판(38)의 노출면(41)로부터 외부로 돌출하는 보스(42)은 내부 나선보어(44)를 포함하고 하부판(40)은 보스(42)에 대해 공통 축상으로 장치되는 외부나선스터드(46)를 포함한다.The boss 42 protruding outward from the exposed surface 41 of the upper plate 38 includes an inner spiral bore 44 and the lower plate 40 has an outer spiral stud mounted on a common axis with respect to the boss 42. 46).

상부 및 하부판(38) 및 (40)은, 각각, 강(steel)으로 형성되는 것이 바람직하고, 탄성중합체패드(36)이 그 사이에 삽입된다.The upper and lower plates 38 and 40 are each preferably formed of steel, and an elastomeric pad 36 is inserted therebetween.

본 발명에 따라, 제2도, 제3도,제6도,제7도 및 8도에 도시된 바와같이, 베어링아답터(32)는 베어링(26)위에 적절하게 시이트되는 하부오목표면(48)을 갖는 블록모양이다.According to the invention, as shown in FIGS. 2, 3, 6, 7, and 8, the bearing adapter 32 is a lower misaligned surface 48 suitably seated on the bearing 26. Block shape with

탄성중합체장치(34)의 하부판(40)의 접촉면(52)와 접촉하는 평접촉 표면(50)이 맞서는 쪽에 형성된다.A flat contact surface 50 in contact with the contact surface 52 of the lower plate 40 of the elastomeric device 34 is formed on the opposite side.

접촉표면(50)은 탄성중합체 장치표면(52)와 근본적으로 면-면접촉을 확실하게 하기 위하여 기계마무리작업을 해주는 것이 바림직하다. 베어링아답터(32)의 측부로부터 돌출한 드러스트 러그(53)은 받침대 러그(28)위의 드러스트러그(54)와 함께 작동하여 베어링아답터(32)의 측면운동을 제한한다. 또한, 드러스트슐터(56)은 드러스트러그(54)와 상호작동하여 베어링아답터(32)의 종운동을 한정한다. 제8도에 되시된 바와같이, 베어링아답터(32)의 접촉표면(50)은 원형이 바람직하다.The contact surface 50 is preferably machined to ensure essentially surface-to-face contact with the elastomeric device surface 52. A thrust lug 53 protruding from the side of the bearing adapter 32 works with the thrust lug 54 on the pedestal lug 28 to limit the lateral motion of the bearing adapter 32. In addition, the thruster 56 cooperates with the thruster 54 to limit the longitudinal motion of the bearing adapter 32. As shown in FIG. 8, the contact surface 50 of the bearing adapter 32 is preferably circular.

내부나선홀(58)은 표면(50)을 관통하여 아답터내로 공통축을 갖고 확장된다.The inner spiral hole 58 penetrates the surface 50 and extends with a common axis into the adapter.

또한, 제2도와 제3도에 도시된 바와같이, 받침대정부(30)의 하부는 탄성중합체장치(34)의 표면(41)과 접촉하는 평표면(60)이 제공되도록 기계마무리 가동되는 것이 바람직하다.Also, as shown in FIG. 2 and FIG. 3, the lower part of the pedestal 30 is preferably mechanically operated to provide a flat surface 60 in contact with the surface 41 of the elastomeric device 34. Do.

접촉표면(60)은 베어링아답터표면(50)과 동일하게 모양화될 수 있다. 개구(62)는 받침대정부(30)을 관통확장하여 탄성중합체장치의 보스(42)를 수용하고 보스(42)와 개구(62)사이에 틈새가 존재하여 휠세트가 볼트의 고정에 앞서서 정확하게 끼워질 수 있다. 탄성중합체장치(34)는 외부나선스터드(46)이 베어링아답터(32)의 내부나선홀(58)에 나사고정되므써, 사이드프레임(12)와 휠세트(14)사이에서 고정된다.The contact surface 60 may be shaped identically to the bearing adapter surface 50. The opening 62 penetrates the pedestal part 30 to accommodate the boss 42 of the elastomeric device, and a gap exists between the boss 42 and the opening 62 so that the wheel set is correctly fitted before fixing the bolt. Can lose. The elastomeric device 34 is fixed between the side frame 12 and the wheel set 14 by the outer spiral stud 46 being screwed into the inner spiral hole 58 of the bearing adapter 32.

탄성중합체장치(34)가 아답터(32)에 견고하게 나사고정되므로 접촉표면(50) 및 (52)가 확고한 비활주결합 상태로 유지된다.Since the elastomeric device 34 is firmly screwed into the adapter 32, the contact surfaces 50 and 52 remain in a firm non-slid state.

보스(42)는 받침대정부개구(62)내로 삽입되고 나선볼트(64)는 내부 나선보어(44)에 나사고정된다. 비교적 두꺼운 와셔(68)은 받침대정부(30)과 볼트(64)의 헤드(66) 사이에 장치된다.The boss 42 is inserted into the pedestal opening 62 and the threaded bolt 64 is screwed into the inner spiral bore 44. A relatively thick washer 68 is installed between the pedestal 30 and the head 66 of the bolt 64.

볼트(64)는 와셔(68)에 충분한 크램핑력(clamping force)이 부여되도록 견고하게 고정되므로 받침대접촉면(60)에 대한 탄성중합체장치 접촉표면(41)의 상대운동이 방지된다. 외부나선스터드(46)과 나선볼트(64)는 동일한 방향의 나선 즉, 둘다 왼쪽이든지 또는 둘다 오른쪽방향의 나선을 포함한다. 상기와 같이 동일한 방향의 나선을 갖는다는 것은 매우 중요한데, 그 이유는 휠세트와 사이드프레임이 맞서는 방향으로 상대회전되는 경우 나선장치의 어느 하나는 조여지게 되므로 스터드(46) 또는 볼트(64)의 나선장치가 풀릴려는 어떠한 경향도 저지되기 때문이다. 작동에 있어서, 탄성중합체 장치(34)의 탄성중합체패드(36)은 직선철로를 따라 대차가 운행되는 경우, 휠세트(14)가 사이드프레임(12)에 대해 근본적으로 직각관계를 유지하도록 하여 헌팅방지에 기여함으로써 헌팅현상을 제한하는 역활을 한다.The bolt 64 is firmly fixed to impart sufficient clamping force to the washer 68, thereby preventing relative movement of the elastomeric device contact surface 41 with respect to the pedestal contact surface 60. The outer spiral stud 46 and the spiral bolt 64 include spirals in the same direction, ie both left or spirals in the right direction. It is very important to have the spirals in the same direction as above, because one of the helixes is tightened when the wheelset and the side frame are rotated relative to each other, so that the spirals of the stud 46 or the bolt 64 This is because any tendency to unwind the device is prevented. In operation, the elastomeric pad 36 of the elastomeric device 34 allows the wheelset 14 to remain essentially perpendicular to the sideframe 12 when the bogie runs along a straight rail. By contributing to prevention, it plays a role of limiting hunting phenomenon.

또한, 탄성 또는 탄성중합체패드(36)는 차측(16)과 사이드프레임(12)의 상대제한회전을 허용하여, 곡선철로를 따라 대차가 운행되는 경우, 완충을 용이하게 해준다.In addition, the elastic or elastomeric pad 36 allows relative limited rotation of the vehicle side 16 and the side frame 12 to facilitate cushioning when the bogie runs along a curved track.

대차가 직선철로로 복귀하는 경우, 패드(36)이 작동하여 차축(16)과 사이드프레임(12)를 그들의 직각관계로 복귀시킨다.When the bogie returns to the straight rail, the pad 36 is operated to return the axle 16 and the side frame 12 to their right angle relationship.

철도차량의 운행중, 수평력이 대차 및 차체의 발생되므로 탄성중합체 패드(36)이 전단변형되어 휠세트가 차량상부 장치로부터 분리되므로 향상된 요우잉 및 차량의 측 안정성이 제공된다.During the operation of the railway vehicle, the horizontal force is generated in the bogie and the vehicle body, so that the elastomeric pad 36 is sheared so that the wheelset is separated from the upper vehicle apparatus, thereby providing improved yawing and vehicle side stability.

또한, 탄성중합체패드(36)은 휠세트의 한정된 회전을 허용한다.The elastomeric pad 36 also allows for limited rotation of the wheelset.

본 발명장치는 탄성중합체장치(34)가 사이드프레임(12)와 베어링아답터(32)사이에서 고정되어 전영역에 걸쳐서 접촉표면(50-52)와 (41-60)사이의 어떠한 분리도 발생되지 않음을 특징으로 한다.In the present invention, the elastomeric device 34 is fixed between the side frame 12 and the bearing adapter 32 so that no separation between the contact surfaces 50-52 and 41-60 occurs over the entire area.
